Solar Panel Battery Storage
Store the energy your solar panels generate during the day and use it whenever you need it. Battery storage helps you maximise your savings, reduce your reliance on the grid and get the most from every kilowatt your system produces.
Make the Most of Every Ray of Sunshine
During the day, your solar panels often generate more electricity than your household uses, especially when the family is out at work or school. Without a battery, that surplus is sent to the grid for just a few pence per unit. With battery storage, you keep that energy and use it in the evening when you are actually home, cooking dinner, watching television, running the washing machine or charging your electric vehicle overnight.
A home battery sits quietly in your garage, utility cupboard or on an outside wall. It charges automatically whenever your panels produce more than you need and discharges the moment your consumption exceeds generation. During a power cut, certain battery systems can keep your lights, fridge and internet router running until the grid comes back online, a feature that is increasingly valued by families across the UK.
We size every battery to match your specific household routine. A family that is out during the day and home in the evening has different storage needs to a household with someone working from home. Our MCS certified engineers analyse your monitoring data and energy bills to recommend the right capacity, ensuring you store enough to cover your peak evening usage without overspending on a battery that is larger than you need.
Benefits of Solar Battery Storage
Adding a battery to your solar panel system transforms how you use energy. Here are six reasons homeowners across the UK are making the switch.
Store Excess Energy
Rather than sending surplus solar electricity back to the grid for pennies, a battery captures it for your own use later. You keep the energy you have already paid to generate, making your solar panels work harder for you throughout the entire day.
Use Power at Night
Solar panels only generate electricity during daylight hours, yet most household energy consumption happens in the evening. Battery storage bridges that gap, letting you power your home with clean solar energy long after the sun has set.
Reduce Grid Dependence
The less electricity you draw from the grid, the less vulnerable you are to rising energy prices. A well-sized battery system can significantly reduce your grid imports, giving you greater control over your energy costs month after month.
Maximise SEG Earnings
With a battery, you can choose when to export electricity under the Smart Export Guarantee, timing your exports for the most favourable rates rather than sending power to the grid automatically whenever your panels overproduce.
Blackout Protection
Certain battery systems offer emergency backup functionality, keeping essential circuits running during power cuts. While not a full off-grid solution, this feature provides valuable peace of mind during unexpected outages.
Future-Proof Your Home
As the UK transitions towards electrified heating and transport, household energy demand will only grow. Installing battery storage now positions your home to handle future loads such as heat pumps and electric vehicle charging more efficiently.
How Battery Storage Works
Solar battery storage is straightforward. Your system follows three simple steps to capture, store and deliver clean energy exactly when your household needs it.
Solar Panels Generate
During daylight hours, your solar panels convert sunlight into electricity. Your home uses what it needs in real time, powering appliances, lighting and heating directly from your roof. Any electricity that exceeds your immediate demand becomes surplus energy ready to be stored.
Battery Stores Excess
Instead of exporting surplus energy to the grid, your battery automatically absorbs it. The system charges throughout the day whenever generation outpaces consumption, building up a reserve of clean, free electricity that belongs entirely to you.
Use When You Need It
When the sun goes down or your energy demand spikes in the evening, the battery discharges its stored electricity to power your home. You draw from your own reserve first, only pulling from the grid if your battery runs empty. The result is lower bills and greater energy independence.
Key Considerations for Battery Storage
Choosing the right battery system depends on several factors. Here is what we assess during every consultation to ensure you get the best solution for your home.
Battery Capacity
Battery capacity is measured in kilowatt hours (kWh) and determines how much energy you can store. A typical UK household uses between 8 and 10 kWh per day, so we recommend a battery sized to cover your evening and overnight consumption. We analyse your energy usage patterns to specify the ideal capacity for your needs.
Compatibility
Battery storage works with both new solar panel installations and existing systems. Whether you had panels fitted last year or a decade ago, we can retrofit a compatible battery to your current setup. Our team checks your inverter type, wiring configuration and available space to ensure a seamless integration.
Lifespan & Warranty
The lithium-ion batteries we install are built to last, with most manufacturers offering warranties of 10 to 15 years or a guaranteed number of charge cycles. In practice, a quality battery will retain at least 70% of its original capacity well beyond the warranty period, delivering reliable performance for years to come.
Smart Energy Management
Modern battery systems come with intelligent software that learns your usage patterns and optimises charging and discharging automatically. Many include smartphone apps giving you real-time visibility of generation, storage levels and consumption, putting you firmly in control of your household energy.
